为什么改成被注释部分的代码，会造成数据库报错？

namespace ET

{

// 可以用来管理多个客户端场景，比如大世界会加载多块场景

[ComponentOf(typeof(Scene))]

public class CurrentScenesComponent: Entity, IAwake

{

    public Scene Scene { get; set; }

    /\*

    private Scene m_scene = null;

    public Scene Scene 

    {

        get { return m_scene; }

        set 

        {

            Log.Info($"CurrentScenesComponent.Scene : set : ({value})");

            m_scene = value;

        }

    }

    \*/

}

}
